Improvements
Added a CodeCompletion shell on top of the existing ones to allow a more generic IDE support from now on.
You can generate a basic file that any IDE should understand. With this you can provide correct typehinting now for a lot of magic properties and methods that so far haven't worked.
See the documentation on details - and on how to write your own custom (project/plugin) tasks on top!
Give it a try - and let me know in the Wiki or via PR (pull request) if your IDE works out or what might still be missing.
